After getting the YellowKey and returning to the two doors, yellow says he can't get into "the ol' yeller room." Which is a reference to the Western drama film Old yeller, which ends with the titular dog being put down like Yellow plans to be.

I really have no time with man-children who have no professional courtesy. But for followers’ information and not his, the YellowKey backdoor requires holding the Ctrl key during the WinRE startup sequence. That shows a specific intent.
You made a specific claim of intent. This doesn't support the conclusion you made.

Zero-Day Exploit Against Windows BitLocker
It's nasty, but it requires physical access to the computer: The exploit, named YellowKey, was published earlier this week by a researcher who goes by the alias Nightmare-Eclipse. It reliably bypasses default Windows 11 deployments of BitLocker, the full-volume encryption protection Microsoft provides to make disk contents off-limits to anyone without the decryption key, which is stored in a secured piece of hardware known as a trusted platform module (TPM). BitLocker is a mandatory protection for many organizations, including those that contract with governments. Slashdot thread. And here's Nightmare-Eclipse's GitHub account.

BitLockerすり抜ける「YellowKey」脆弱性。発見者曰く「意図的なバックドア」
BitLockerで暗号化されたドライブは安全――その常識を覆す脆弱性が発覚した。過去に複数の脆弱性を発見しているNightmare-Eclipse氏は5月13日、「YellowKey」と呼ばれるWindows 11のBitLockerをすり抜ける脆弱性を公開した。同氏はこれを脆弱性ではなく、意図的に仕込まれた「バックドア」だという見方を示している。
